What is Citric acid monohydrate？
Citric acid monohydrate is an organic compound with a molecular formula of C6H10O8. It is mainly used in food and beverage industry as an acid flavor agent, flavoring agent, preservative and fresh-keeping agent. It is also used as antioxidant, plasticizer and detergent in chemical industry, cosmetics industry and washing industry.
Citric Acid Monohydrate is a tricarboxylic acid found in citrus fruits. Citric acid is used as an excipient in pharmaceutical preparations due to its antioxidant properties. It maintains stability of active ingredients and is used as a preservative. It is also used as an acidulant to control pH and acts as an anticoagulant by chelating calcium in blood.
Citric acid monohydrate - Properties
Citric acid monohydrate - Preparation method
Colorless orthogonal columnar crystals or white crystalline particles. It is easy to weather in dry air and to clump in moist air. Soluble in water and ethanol, slightly soluble in ether.
Using saccharide solution as raw material, it was prepared by fermentation, separation and purification of black kojase strain. Or from the citric acid containing fruit, such as lemon juice (citric acid can be 5% ~ 8%), pineapple directly extracted.
Citric acid monohydrate Action:
Citric acid monohydrate because of its non-toxic, good solubility, delicious sour taste, excellent derivatives and other properties of food industry, medicine, cosmetics and oral chemical industry.
Citric acid monohydrate is mainly used in food and beverage, as a flavoring agent, sour agent and preservative. Citric acid is a very important organic acid, and in the physiological mechanism, citric acid is an important substance that converts fats and proteins and sugars into carbon dioxide, and this conversion process is the core reaction of all metabolic processes. It also has applications in the chemical and cosmetic industries, as an antioxidant and as a detergent.
Citric acid monohydrate is safe and non-toxic, known as the first edible sour agent, which is widely used in beverage fruit processing, soy products and flavoring agents. Citric acid is widely used in jelly, candy, wine, citric acid added to frozen food, can strengthen the antioxidant effect to inactivate enzymes, to ensure the stability of frozen food.
Citric acid monohydrate is also widely used in various nutritional oral liquid, which is used to adjust the pH value of oral liquid, maintain the stability of ingredients and ensure the nutritional effect. Add citric acid to your shampoo, anti-dandruff shampoo, and hair color solution to adjust pH, increase shine and restore elasticity when shampooing. Citric acid is added to cosmetics and toothpaste to prevent products from breaking down and going bad.
Citric acid is also widely used in chemical industry. Citric acid itself is a chemical synthesis intermediate, is the basic raw material of chemical synthesis. Because of its excellent properties, it is widely used as cleaning agent, stabilizer, chelator and defoamer in the chemical industry. In recent years, with the enhancement of people's awareness of environmental protection, sodium citrate has been more and more widely used in the production of green phosphorus free detergent.
